  • Page 3: Introduction

    1. Introduction The R718EC is identified as a LoRaWAN ClassA device with three-axis acceleration , temperature and is compatible with the LoRaWAN protocol. When the device moves or vibrates over the threshold value, it immediately reports the temperature, acceleration, and velocity of the X, Y, and Z axes.

  • Page 5: Set Up Instruction

    1. Actual range may vary depending on the environment. 2. Battery life is determined by sensor reporting frequency and other variables. 4. Set up Instruction On/Off Power on Insert batteries. (users may need a screwdriver to open) Turn on Press and hold the function key for 3 seconds till the green indicator flashes once. Turn off Press and hold the function key for 5 seconds, and the green indicator flashes 20 times.

    (1) The device report interval will be programmed based on the default firmware which may vary. (2) The interval between two reports must be the minimum time. Please refer Netvox LoRaWAN Application Command document and Netvox Lora Command Resolver http://loraresolver.netvoxcloud.com:8888/page/index...

  • Page 7: Activethreshold And Inactivethreshold

    The 0g offset is an important accelerometer indicator because it defines the baseline used to measure acceleration. After installing R718EC, users need to let the device rest for 1 minute, and then power on. Then, turn on the device and wait for the device to take 1 minute to join the network.

    In the case of detecting if the generator is working normally, it is recommended to install R718EC horizontal while the generator is power-off and in static status. After installing and fixing R718EC, please turn on the device. After the device is joined, one minute later, R718EC would perform the calibration of the device (the device cannot be moved after the calibration.

  • Page 11: Information About Battery Passivation

    7. Information about Battery Passivation Many Netvox devices are powered by 3.6V ER14505 Li-SOCl2 (lithium-thionyl chloride) batteries that offer many advantages including low self-discharge rate and high energy density. However, primary lithium batteries like Li-SOCl2 batteries will form a passivation layer as a reaction between the lithium anode and thionyl chloride if they are in storage for a long time or if the storage temperature is too high.

  • Page 12: Important Maintenance Instruction

    8. Important Maintenance Instruction Kindly pay attention to the following to achieve the best maintenance of the product: • Keep the device dry. Rain, moisture, or any liquid might contain minerals and thus corrode electronic circuits. If the device gets wet, please dry it completely.
